Universal joint shaft with length compensation Universal joint shaft without length compensation

lB: Operating length (to be provided with order.)

lz: Shortest length of the universal joint shaft (collapsed)

lv: Available length compensation

The distance between the driving and driven machines, together with any length changes during operation, determines the operating length:

Optimum operating length: lB,opt ≈ lz + lv __ 3

Maximum permissible operating length: lB,max = lz + lv

lB: Operating length, corresponds to the universal joint shaft length l (to be provided with order.)

5 Definitions and abbreviations5.1 Lengths

Note:

MDW, MDS and MZ are load limits for the

universal joint shaft. For torque values near

the load limit, the transmission capability of the

flange connection must be checked, especially

when Hirth serrations are not being used.

lB,max

lz lv lB (=l)


Designation Explanation

Components

MDW Is the reversing fatigue torque rating. The shaft will have infinite fatigue life up to this torque.

MDS Is the pulsating one-way fatigue torque rating. The shaft will have infinite fatigue life up to this torque level.Here: MDS ≈ 1.5 · MDW

MK Maximum permissible torque. Above this value, plastic deformation may occur.

Bearing

MZ Permissible torque for rarely occurring peak loads. At torque values above MZ, the bearing tracks might suffer from plastic deformation. This can lead to shorter bearing life.

7.6 Safeset safety couplings

Three-dimensional section through a Safeset safety coupling (type SR-C)

Description

The Safeset coupling is a torque-

limiting safety coupling that imme-

diately interrupts the power trans-

mission of the drive line in the event

of an overload, thus protecting all of

the components such as motor,

gearbox, universal joint shafts etc.

against damage.

Placing the safety coupling between

the joints, what is known as Voith

"integral design", provides smaller

deflection angles in the joints and

thus a longer lifetime of drive line

components.

8.2 Length compensation with SAE or involute profile

Involute profileSAE profile (straight flank profile)

Length compensation is required in the universal joint shaft for many

applications. In contrast to other drive elements, length compensation in the

center section and offset are achieved through the joints for universal joint

shafts.

Two types of length compensation are utilized in Voith universal joint shafts:

the SAE profile (straight flank profile) and the involute profile. The universal

joint shaft series and size determine the type of length compensation.

For the loads experienced by smaller universal joint shafts, the involute profile

is a suitable solution with a good cost/benefit ratio. The SAE profile (straight

flank profile) is a better solution for large high-performance universal joint

shafts.


Length compensation with SAE profile (straight flank profile)

n Straight flank diameter-centered profile n Separation of torque transmission and centering functions n Long service life

n Almost orthogonal introduction of force n Low normal forces and thus lower displacement forces n Moves easily

n Large contact surfaces n Low surface pressure n Long service life

n Favorable pairing of materials for hub and spline shaftn Spline shaft nitrated as standard

n High wear resistance n Long service life

n Patented lubricating mechanism in the grease distribution groove for uniform distribution of grease over the entire diameter of the profile

n Tooth shape incorporates lubricant reservoir for reliable supply of lubricant to sliding surfaces

n Extended maintenance intervals

8.3 Kinematics of the universal joint

n When the input shaft W1 rotates at a constant angular

velocity (v1 = const.), the output shaft W2 rotates at a

varying angular velocity (v2 ≠ const.).

n The angular velocity of the output shaft v2 and the

differential angle w = (a1 – a2) vary in a sinusoidal

manner, their values depend on the deflection

angle b.

n This characteristic of a universal joint is called the

gimbal error and must be taken into consideration

when selecting a universal joint shaft.

n With one rotation of the shaft W1, the differential

angle w changes four times as does the angular

velocity v2.

n During one rotation, the shaft W2 passes through the

points of maximum acceleration and deceleration

twice.

n At larger deflection angles b and higher velocities,

considerable forces can be generated.

The following equations apply:

w = a1 – a2 (1)

tan a1 _____ tan a2

= cos b (2)

tan w = tan a1 · (cos b – 1)

________________ 1 + cos b · tan2 a1 (3)

This results in the ratio of the angular velocities

between the two shafts W1 and W2:

= cos b

_______________ 1 – sin2 b · sin2 a1

and the minimum

v2 ___ v1

| min = cos b bei a1 = 0° and a1 = 180° (4b)

For the torque ratio, the following equation applies:

M2 ___ M1

= v1 ___ v2

(5)

with the maximum

M2 ___ M1

| max = 1 _____ cos b bei a1 = 90° and a1 = 270° (5a)

Conclusion

A single universal joint should be used only if the

following requirements are satisfied:

n The variation in rotational speed of the output shaft

is of secondary importance

n The deflection angle is very small (b < 1°)

n The forces transmitted are low.

8.4 Double universal joints

Section 8.3 shows that the output shaft W2, when

connected via a single universal joint at a given

deflection angle b, always rotates at the varying

angular velocity v2.

If, however, two universal joints G1 and G2 are con-

nected together correctly in the form of a universal

joint shaft in a Z or W arrangement, the variations

in the speeds of the input and output shaft cancel

each other completely.

Universal joint shaft in Z arrangement, input and output shafts lie parallel to one another in one plane

Universal joint shaft in W arrangement, input and output shafts intersect one another in one plane

Conditions for synchronous rotation of the input

and output shafts:

The three conditions A, B and C ensure that joint G2

operates at a phase shift of 90° and completely com-

pensates for the gimbal error of joint G1. This universal

joint shaft arrangement is called the ideal universal joint

shaft arrangement with complete motion compensation.

It is the arrangement to strive for in reality. If only one of

the three conditions is not satisfied, the universal joint

shaft no longer operates at constant input and output

speeds, i.e. no longer operates homo-kinetically. In

such cases, please contact your Voith Turbo repre-

sentative.

8.5.2 Axial bearing forces

In principle, the kinematics of a universal joint shaft

do not generate any axial forces. Nevertheless, axial

forces that must be absorbed by the connection

bearings arise in universal joint shafts with length

compensation for two reasons:

1. Force Fax,1 as a result of friction in the length

compensation assembly

As the length changes during transmission of torque,

friction is generated between the flanks of the spline

profiles in the length compensation assembly. The

frictional force Fax,1, which acts in an axial direction,

can be calculated using the following equation:

Fax,1 = m · Md · 2 ___ dm

· cos b

Where:

m Coefficient of friction

m ≈ 0.11…0.14 for steel against steel (lubricated)

m ≈ 0.07 for Rilsan® plastic coating against steel

Md Input torque

dm Pitch circle diameter of the spline profile

b Deflection angle

2. Force Fax,2 as a result of the pressure build-up

in the length compensation assembly during

lubrication

During lubrication of the length compensation

assembly, an axial force Fax,2 arises that depends

on the force applied while lubricating. Please note,

information with regard to this subject is available

in the installation and operating instructions.

8.6 Balancing of universal joint shafts

As with any other rotating equipment, a universal joint

shaft has a non-uniform distribution of mass around

the axis of rotation. This leads to unbalanced forces

during operation. Depending on the operating speed

and the specific application, Voith universal joint

shafts are dynamically balanced in two planes.

Depending on the application and maximum operating

speed, balance quality levels for universal joint shafts

lie in the range between G 40 and G 6.3. The repro-

ducibility of measurements can be subject to wider

tolerances due to the influence of various physical

factors. Such factors include:

n Design characteristics of the balancing machine

n Accuracy of the measurement method

n Tolerances in the connections to the universal

joint shaft

n Radial and axial clearances in the universal

joint bearings

n Deflection clearance in the splined center section

The benefits of balancing:

n Avoidance of vibrations, resulting in smoother

operation

n Longer lifetime of the universal joint shaft

The balancing procedure employed by Voith for

universal joint shafts is based on that prescribed

in DIN ISO 1940-1 ("Mechanical vibration – Balance

quality requirements for rotors in a constant (rigid)

state – Part 1: Specification and verification of balance

tolerances"). An extract from this Standard lists the

following approximate values for balance quality levels:


9 Selection aids

The design of a universal joint shaft depends on a number of factors.

Reliable, verified calculations and tests prevent any danger to the

surrounding area. Consideration of the costs that arise during the entire

product lifecycle also comes into play.

The design procedures described in this chapter are merely rough

Explanation

nz1 [rpm] Maximum permissible speed as a function of the deflection angle during operation.The center section of a universal joint shaft in a Z or W-arrangement (b ≠ 0°) rotates at a varying speed. It experiences a mass acceleration torque that depends on the speed and the deflection angle. To ensure smooth operation and prevent excessive wear, the mass acceleration torque is limited by not exceeding the maximum speed of universal joint shaft nz1. For additional information, see Section 9.3.1.

nz2 [rpm] Maximum permissible speed taking bending vibrations into account.A universal joint shaft is an elastic body when bent. At a critical bending speed, the frequency of the bending vibrations equals the natural frequency of the universal joint shaft. The result is a high load on all of the universal joint shaft components. The maximum speed of the universal joint shaft must be considerably below this critical speed. For additional information, see Section 9.3.2.

b [°] Deflection angle during operationDeflection angle of the two joints in a Z or W-arrangement, where:

b = b1 = b2

If the situation involves three-dimensional deflection, a resultant deflection angle bR is determined:

9.2.1 Selection on the basis of bearing lifetime

The procedure used for calculating the bearing lifetime

is based on that prescribed in DIN ISO 281 ("Rolling

bearings – Dynamic load ratings and rating life"). How-

ever, when applying this standard to universal joint

shafts, several different factors are not taken into

account, for instance, support of the bearing, i.e.

deformation of the bore under load. To date, these

factors could only be assessed qualitatively.

The theoretical lifetime of a bearing in a universal

joint shaft is calculated using the following equation:

Lh = 1.5 · 107

_________ nE · b · KB · ( CR ___ ME

) 10 ___ 3

where:

Lh is the theoretical lifetime of the bearing

in hours [h]

CR Load rating of the universal joint in kNm

(see tables in Chapter 6)

b Deflection angle in degrees [°]; in the case

of three-dimensional bending, the resultant

deflection angle bR is to be used; in any case,

however, a minimum angle of 2°

KB Operational factor

nE Equivalent speed in rpm

ME Equivalent torque in kNm

9.2 Size selection

Operational factor

In drives with diesel engines, torque spikes occur that

are taken into account by the operational factor KB:

Prime mover (driving machine) Operational factor KB

Electric motor 1

Diesel engine 1.2

There are essentially two selection criteria when choosing the size of a universal joint shaft:

1. The lifetime of the roller bearings in the joints

2. The fatigue-free operating range, and thus the torque capacity and/or load limits

As a rule, the application determines the primary selection criterion. A selection on the

basis of bearing lifetime is usually made if drives must have a long service life and pro-

nounced torque spikes never occur or occur only briefly (for instance, during start-up).

Typical examples include drives in paper machines, pumps and fans. In all other appli-

cations, selection is made on the basis of the fatigue-free operating range.

Conclusions

n The calculated lifetime of the bearing is a theoretical

value that in practice is usually exceeded by a con-

siderable amount.

n The following additional factors affect the lifetime of

the bearings, sometimes to a significant degree:

– Quality of the bearings

– Quality (hardness) of the journals

– Lubrication

– Overloading that results in plastic deformation

– Quality of the seals

Equivalent operating values

The equation for the theoretical lifetime of the bearing

assumes a constant load and speed. If the load changes

in increments, equivalent operating values that produce

the same fatigue as the actual loads can be determined.

The equivalent operating values are ultimately the

equivalent speed nE and the equivalent torque ME.

If a universal joint shaft transmits the torque Mi for a time

period Ti at a speed ni, a time segment qi that normalizes

the time period Ti with respect to the overall duration of

operation Tges is first defined:

qi = Ti ____ Tges

with ∑ i = 1

u

qi = q1 + q2 + … + qu = 1

In this way, the equivalent operating values can be

determined:

nE = ∑ i = 1

u

qi · ni = q1 · n1 + q2 · n2 + … + qu · nu


9.2.2 Selection on the basis of fatigue-free

operating range

Calculations regarding the fatigue-free operating range

can be performed using a load spectrum. In practice,

however, sufficiently accurate load spectra are seldom

available. In this case, one relies on the quasi-static

dimensioning procedure. Here, the expected peak

torque Mmax is compared with the torques MDW, MDS

and MZ (see Section 5.2).

The following estimate is made for the peak torque:

Mmax ≈ K3 · MN

K3 is called the shock factor. These are empirical values

based on decades of experience in designing universal

joint shafts.

The peak torque determined in this manner must

satisfy the following requirements:

1. Mmax < MDW for alternating load

2. Mmax < MDS for pulsating load

3. Individual and rarely occurring torque spikes must

not exceed the value MZ. The permissible duration

and frequency of these torque spikes depends on

the application; please contact Voith Turbo for more

information.

In addition, the mass acceleration moment can affect

the entire drive line on universal joint shafts with length

compensation as well as universal joint shafts without

length compensation. Torsional vibrations should be

mentioned here by way of example.

To prevent these adverse effects, please comply with

the following conditions:

nmax < nz1

9.3.1 Maximum permissible speed nz1 as a

function of deflection angle during

operation

Section 8.3 shows that a universal joint exhibits a

varying output motion. A universal joint shaft is a

connection of two universal joints in series with one

another. Under the conditions described in Section 8.4,

a universal joint shaft in a Z or W arrangement exhibits

homokinetic motion between the input and output.

Nevertheless, the center section of the universal joint

shaft still rotates at the periodically varying angular

velocity v2.

Since the center section of the universal joint shaft still

exhibits a mass moment of inertia, it creates a moment

of resistance to the angular acceleration dv2 /dt. On

universal joint shafts with length compensation, this

alternating mass acceleration moment can cause

clattering sounds in the profile. The consequences

include less smooth operation and increased wear.

The maximum permissible speed nz2 is determined in

such a way that provides a safety allowance with re-

spect to the critical bending speed that is suitable for

the particular application.

For safety reasons and to prevent failure of the uni-

versal joint shaft, please comply with the fol lowing

conditions:

nmax < nz2

For normal connecting and operating conditions, it is

possible to specify approximate values for the max-

imum permissible speeds nz2 as a function of operating

length lB:

9.3.2 Maximum permissible speed nz2

as a function of operating length

Every universal joint shaft has a critical bending speed

at which the rotational bending speed (bending fre-

quency) matches the natural frequency of the shaft. The

result: high loads on all components of the univer sal

joint shaft. Damage to or destruction of the universal

joint shaft is possible in unfavorable situations.

Calculating this critical bending speed for a real uni-

versal joint shaft in a drive line is a complex task that

Voith Turbo performs using numerical computing

programs.

The critical bending speed depends essentially on three

factors:

n Operating length lBn Deflection resistance of the universal joint shaft

n Connecting conditions at the input and output ends

When installing the Voith universal joint shaft in a drive

line, connecting flanges and bolted connections must

satisfy several requirements:

1. Design

n When using a universal joint shaft without length

compensation, a connecting flange ("roll end hub")

that is moveable in a longitudinal direction is required

so that the universal joint shaft can slide over the

spigot. The connecting flange also absorbs additional

length changes arising, for instance, from thermal

expansion or changes in the deflection angle.

2. Material

n The material used for the connecting flanges has

been selected to permit use of bolts in property class

10.9 (to ISO 4014-10.9).

n Special case for S, M and W Series:

If the material used for the connecting flanges does

not permit use of bolts in property class 10.9, the

torque that can be transmitted by the flange con-

nection is reduced. The specified tightening torques

for the bolts must be reduced accordingly.

3. Dimensions, bolted connections

n On universal joint shafts from the S, M and W Series,

the dimensions of the connecting flanges match

those of the universal joint shaft, except for the

locating diameter c. The locating diameter provides

a clearance (fit H7/h6).

n On universal joint shafts from the H Series, the dimen-

sions of the connecting flanges are identical to those

of the universal joint shaft. The Hirth couplings are

self-centering.

n On universal joint shafts from the S, M and W Series,

the relief diameter fg on the universal joint shaft

flange is not suitable for locking hexagon head bolts

or nuts. A relief diameter fa on the connecting flange

is suitable for this purpose.

11 High-performance lubricant for universal joint shafts

Voith development engineers have combined their universal joint

shaft know-how with the tribological know-how of renowned bear-

ing and lubricant manufacturers. The result of this cooperation is

an innovative and exclusive lubricant with properties far above

those of conventional standard lubricants. This lubricant gives

bearings in universal joint shafts operating at low speeds and

under high loads an even longer life. In addition, lubrication inter-

vals are extended and emergency dry-running characteristics im-

proved significantly.

Flange for a high-performance universal joint shaft on a 3-D coordinate measuring machine

n We employ state-of-the-art 3-D coordinate measuring

machines for quality assurance.

n To ensure perfectly welded joints, we conduct x-ray

inspections in-house.

n We offer our customers a variety of product and

application-specific certifications and classifications.

n Production and assembly fixtures are inspected on a

regular basis.

n Quality-relevant measuring and testing instruments

are subject to systematic monitoring.

to ISO SO 3834-2 are used. Welding technicians are

qualified to EN 287 and welding equipment is

monitored.

n Employees that perform nondestructive testing are

qualified to ASNT-C-1A and/or EN 473.


12.2 Environment

n Voith universal joint shafts are fitted with sealed roller

bearings. These provide two major advantages over

slipper and gear spindles when using our universal

joint shafts:

1. Lubricant consumption is considerably lower be-

cause of the seals.

2. Efficiency is enhanced, as rolling friction is signifi-

cantly less than sliding friction. This translates into

reduced CO2 emissions and protects the environ-

ment.


Voith universal joint shafts receive their final finish in a modern paint booth

12.3 Occupational health and safety

n Voith painting technicians use a modern painting

system that meets all requirements for occupational

health and safety as well as environmental protection

when painting the universal joint shafts.

n Electrostatic application of the paint reduces over-

spray.

n An exhaust system extracts any residual mist from

painting.

n An exhaust air treatment system with combined heat

recovery reduces the impact on employees as well as

the environment.
